My all time favorite band. Bill really needed one of Bonham's huge bass drums to capture the sound he was looking for.

I always thought the story in this song could have made a great movie. Man goes to the future, see apocalypse, altered by time travel, tries to warn mankind, shunned because of his transformation, loses his mind and begins the apocalypse he tried to stop. It's a great story but would never work because there is no happy ending.
